London projects often mean working on period terraces with neighbours on both sides, tight access through the house and conservation area controls, so careful planning and party wall work matter as much as the build.

What is a kitchen extension?

A kitchen extension is a single-storey extension designed around a new kitchen, usually creating an open-plan kitchen, dining and family space that opens onto the garden. Planning the kitchen layout at the same time as the building means the drains, steels, windows and power end up where the kitchen needs them.

What approvals does a kitchen extension need in England?

English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.

In England a single-storey rear extension can often go ahead under permitted development: up to 3 m deep on an attached house or 4 m on a detached one, no higher than 4 m, with eaves no higher than 3 m within 2 m of a boundary. Deeper extensions, up to 6 m or 8 m, need prior approval from the council first.

What can change the price or programme?

Islands with sinks or hobs need drainage and power routed in the slab.
Worktops are templated after the units are fitted, adding a short gap before completion.

They follow the same rules as any single-storey extension. Many in England are permitted development.
